KNOW ALL MEN BY THESE PRESENTS:

That I, RICHARD FLYNN, of West Brookeld, in the c ounty of Worcester, and Commonwealth of Massachusetts, have invented certain new and useful .improvements in Steak-Mashers3 and I do herebydeclare that the f0llowing is afnll, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part ofthis specification, iiiwliieh-4 Figure 1 represents a front vieiv of'my, improvedstealc-masher, and i Figure 2 represents a section on line A fig. 1.

To venable those skilled in the art to which my invention helene-sto make and use the same, I will proceed to describe it more in detail. I

In the drawings, A are the steakmasl1ihg rolls, thejournals of which aresupported in suitable bearings tted in slots a in the end pieces B B, which are fastened at thebottorn to the base-piece C, and are united'at the top bya cross-piece, D. c, l

The rolls A A are provided fromend to end with spiral-screw grooves b, which run around the'periph'eri'es 4of lthe rolls a little vobliquely to axis of motion of said rolls. The spiral grooves b are cut o r intersected by parallel V-shaped grooves, c. The spirals, 6, of each roll run in the same direction, as shown in the drawings,

for the purpose hereinafter mentioned. 4 l

The journals of the upper rolls are supported in boxes, which rest upon springs d, while the said boxes are forced down by the curved spring E, the ends of which rest upon the boxes or bearings of the journals of the top roll, `while said spring is forced down by a thumb-screw, F, which passes through the cross-piece Das fully indicated in iig. 1.

The journals G G of rolls A A are provided with gears HH, which mesh in with each other. LA hand-` crank, I, is attached to the end of the journal of thevbottom roll.

The operation is as follows: Theoperator standing in front of the machine, by meais ofthe crank I turns the steak-mashing rollsA A, so as to have the lower surface of the lower roll and the upper surface of the upper roll'turn-towards him. 'lhe steak beingentered or fed in between the rolls, is carried throughV and mashed bythe 'peculiar-shaped surface ofthe rolls A A, K vlierehy it is renderedvery tender when properly cooked hud prepared for the table.

The operation of mashingby the peculiarly-shaped surface of the rolls, causesA the 'steak -to be partially rolled laterally, both at top and bottom, as it is i'cd through the rolls, thereby preventing, in a great measure, 'i

the escape of `the juices of 'the meat.

It will be bserved that the action of the top roll tends to roll the steak in one direction, while the4 lower roll tends to roll it i n the opposite direction, thus rolling and twisting the fibres of the meat at the same time they are mashed.

As soon as the thumb-sereni F is loosened, the springs d elevate the upperroll; the space between therolls can therefore be increased or contracted at pleasures Havingfdescribed my improved steak-masher, what I claim therein as newand ofmy invention, and desire Y to secure by Letters Patent, is-

The employment, in a steak-meshing machine, ofthe rolls A A, the teeth of which are arrangedso as to form' a continuous spiralfrom lone end to the otherof each roll, thc said rolls being geared together Vso as to move in opposite'directions, while their lspirals run in the same direction, as shown and set fortli.
